1. Constant variation
2. D when O = 7 and G = 6
3. O and D = 120 and G = 4
4. G when D = 80 and O = 8

Answer:

1. 10

2. 420

3. 3

4. 1

Step-by-step explanation:

D=KOG

60=k(3)(2)

60=6k

60/6=6k/6

k=10

D=10OG O=7,G=6

D=10(7)(6)

D=10(42)

D=420

D=10OG D=120,G=4

120=10O(4)

120=40O

120/40=40O/40

O=3

D=10OG D=80,O=8

80=10(8)G

80=80G

80/80=80G/80

G=1
